Robust wire measuring machine designed for continuous high speed operation, suitable for cable, rope, tubing or wire up to 15mm in diameter. The 250mm circumference, precision ground measuring wheel runs in self lubricating bearings.The machine is equipped with two adjustable tension springs, mounted externally, which can be unhooked from their anchor. This allows the measuring head to be pivoted up to a backstop to facilitate threading the cable through the machine. When in position, these springs grip the cable between the measuring roller and the bottom roller. They should be adjusted for the minimum tension required to prevent slippage.
